Application led Iay 25, 1986. Serial Io. 111,610.

Thisv invention relates `to thecla'ss of toolsl and pertains particularly to a tool havin an illuminating means associated therewit so that the Working end of the tool may be illuminated when itis necessary to work 4with the same ina position' where there is insufficient light. i

The primary object of thisinvention is the provision, in a manner as hereinafter setforth, of a tool having an illuminatin element associated therewith and so carrie that v the li ht rays from said element will be pro- -jecte directly upon the'working end of the tool.-

Another object ofthe invention is the provision, in a manner as hereinafter set forth, of a tool having an illuminatin element ass'cciated therewith for illuminating the work*- ing end of the tool, and so built in the handle of the tool as to be protected from injury, under all conditions.

The invention particularl the provisionof an illuminating means for a toolY such as a screw driveror drill, havingv directly upon the working end ofthe tool and is not placed in alignment with and behind the end of the shank of 'the working` z member yas inthe case of other tools of this class.

A final object of the invention is the provision, in a manner as hereinafter set forth, of an illuminated tool of the character above described, which lwill be strong and durable and able to stand the usual rough treatment which tools receive without inury to `the illuminating means thereof, an further be light and comparatively inexpensive yto manufactura contemplates (positioned a sleeve having aj over which the cone body is positioned, is.v v"fan electric light element positioned eccen` trically ofthe end of the. body kand bearing-v upon a plate through which a contact is `made with the central electrode of the batlactery. This illuminating element is so. posi- \tioned 4beneath the cone-sha dbody, .thatf `the rays projected from the e ement will fallv Asage of thev contact screw 5.

The invention will be understood from a consideration of the following-detailed de-l scriptiontaken in connection with the accompanying drawing forming a part of this -pecicatiom with the understanding that invention lis not confined to any strict conformity -with the showing of the drawing but may be changed and modified so long as such changes and ymodifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing'z-f Figure 1 shows the tool embod ing vthis inventionxwith the casing handle ereof -in longitudinal section.

Figure 2 is a rear end view of the tool.

' .Fi re 3 is a transversesection taken upon Fi re 4 is a transverse section taken upon the line 4-4 ofFigure 1.

Fi re 5 is a transverse section taken upon the line of Figure 1 and, n

Figure 6 is a transverse section taken upon the yliiie 6-6 of Figure 1.

Referring now to the drawing in detail lwherein -likepnumerals of reference indicate" corresponding parts throughout the several views, the numeral 1 indicates an elon ated ltubular casing which constitutes a com ined tool handle `and receptacle for an elongated cylindrical flashlight battery 2 ofthe usual well known type. As shown the casing 1 isV ofA substantially greater length than thev battery T2 and fitted overl .one end of the'arearlend closure cap 3 havin a recess 4 in the outer end thereof and r-` ther having v extendin through the longitudiiial'y center thereo the Y contact screw 5 .thehead of which is positioned in the recess 4 .below f the outer edge thereof. Interposed between the end of the cap 3 and vthe end of the battery 2, is a spacing washer v6 of insulation material, vhaving a central aperture 7 formed therethrou h r the pasconditions or when the tool is to -be illuminated Afor use,vthe screw 5 is threaded infwardly until contact is made with the meta'lvlic end of the battery` 2 to complete a circuit in a manner hereinafter to be set forth.

nder suitable ionI As is well known batteries of the type here shown are surrounded by a relatively thick wrapper of cardboard 8, which wrapper protects the batteyl'from contact with the metallic wall of `receptacle 1. The central lio electrode 9 of the battery extendsv from the longitudinal center of the other end thereof in the usual manner, as shown in Figure 1.

Overlying the forward end of the battery 2 is an annular copper contactv plate 10 yhaving a central aperture for the 'passage of an electrode 9 of the battery which electrode contacts with the wall of the aperture to make contact with the plate. Positioned againist the inner wall of the handle casing 1 at the forward end of the battery 2, is a thin annular member 11 whicll is secured by the pins 12 to the wall of the casing 1 as-shown in Figure 4. This ring 11 .holds the battery 2 from moving forwardly 1n the casing in the manner shown in Figure 1 and the forward edge of the ring is provided with a notch 13 for the following set forth purpose.

Adapted to be positioned within the forv ward end of the handle casing 1 is an annular plate member 14 having soldered or otherwise secured to the underface thereof the ton ue 15, one end of which overlies the edge o the plate and is adapted to beA positioned in the notch 13 in the ring 11 to hold the plate 14 against revolution when the same is seated upon the end of the ring 11. This plate 14 as is clearly shown in Figures 1 and 5 closes the forward end of the casin 1 forwardly of the battery 2.

Formed throulgmh the plate or disc 14 adjacent the perip ery thereof is an aperture having a sleeve extending outwardly from the edge thereof as indicated at 16, and this sleeve is threaded to receive the base 17 of an incandescent lamp 18.

As is shown in Figure 1, when the disc 14 is in posit-ion and carrying the incandescent bulb 18 in the socket 16, the base portion 17- of the bulb contacts with the plate 10 and is thereby electrically connected with the central electrode 9 of the battery.

As shown the disc 14 is positioned inwardly of the forward end of the handle casing 1 and when thus placed in position there is positioned upon the top of the disc within the end of the casing the retaining resilient split ring member 19. The forward end edge ofthe casing 1 is provided with a notch at the oint-20 for the` purpose hereinafter descri ed.

Adapted to be positioned over the forward end edge of the casing 1 is a sleeve 21 carrying a pin 22 which engages in the notch 20 of the Casin to insure the sleeve being placed thereon in the roper position. Extending f'rom one end) of the sleeve 21 is a cone-shaped body 23 having formed in the wall thereof diametrically oppositely positioned apertures 24 and further havino` extending from the apex thereof a centrally apertured neck 25 adapted toreceive one end of the shank 26 of a screw driver member over one end' of said handle and 27, or any other tool. The retaining posi'- tioning pin 22 carried by the sleeve 21 when in engagement with the notch 20 of the casing 1, so positions the sleeve that one of the apertures 24 of the cone-shaped body .23 directly overlies the incandescent lamp 18 so that it will be readily seen that when the lamp is lighted the rays of light therefrom'will pass directly through thel aperture 24 and fall upon the working end 27 of the tool. It is to be noted that due to the eccentric positioning of the incandescent member 18 all of the light therefrom will fall directly upon t-he work and the working end of the tool.

From the foregoing description it will be readily seen that, upon screwing the contact l vents accidentalcontact of the metal wall of the battery with the casing, the onl contact lthat can be made with the wall of t e casing must be made by means of the contact screw 5 in the end of the tool.

Having thus described my invention what I I claim is 1. A tool of the character described, comprising a handle, a working member, a sleeve at one end of said member for en agement liavin a cone portion extendingtherefrom provi ed with an eccentrically located aperture and adapted to receive said member end, illuminating means within saidcone portion eccentrically of the end of said handle and in alignment with said aperture, for directly illuminating the other end of said member, a battery in said handle and having a center electrode, and a contact element concentrically of and engaged by the illuminating means and the center electrode.

2. A tool of the character described, comprising a handle casing adapted to receive any electric battery having a central electrode,

means forming a continuation of said center electrode, means for maintaining an incandescent bulb eccentrically in one end of said casing in contact with said means, a structure having an eccentrically located aperture enclosing the forward end of Said casing and covering said incandescent bulb, incandescent bulb and said aperture being in alignment, means for holding a working element in said D apertured structure in longitudinal alignment with said casing to receive light rays upon the'working end thereof from said bulb through said aperture in said structure, and

, of said battery an member positioned transversely-vof s'aid casing adjacent said central electrode and bearing uggn and held in position by said notched mem r through engagement with the .notch thereof, an incandescent element carried by battery having a' .ne .mndig through and aim .einem un periphery thereof and contacting with contact late a .working element y apertures body engaging over the end of casing and coveringA said incandescent ele- 20 ment in such manner as to expose the same throu h one of the apertures therein to enable 1 ht ra s therefrom to fall directly upon t e wor end of the working element,l and means for closmgcircult becan nt element 7 tween said battery and in to illuminate the element.

In testimony whereof, I aix my signature hereto. v VINCENT GENOVES.
